Application December 2, 1931, Serial No. 578,546 Renewed May 5, 1934Claims. (01. 126-494) 5 to have the door hinged in such a manner thatthe door will be substantially flush with the wall or door frame of suchrange. If this enamel finish of the outer wall of the door comes intodirect contact with the door frame during the opening and closingmovements of the door there is a likelihood that it may become injured.

It is therefore the object of this invention to devise a novel andsimplified construction of a concealed hinge mechanism for the oven andfire doors of gas and coal ranges which will provide for a full openingof the door, prevent the enameled finish from coming into contact withthe front wall of the range during the opening movement of such door,and also to provide a construction which can be readily assembled.

With the above and other objects in view, as will hereinafter appear, myinvention comprehends novel concealed hinge mechanism for range doors.

It further comprehends a novel hinge mechanism for range doors whereinthe Wall or plate of the range is constructed in a novel manner, andwhich, with the lining of the oven, for example, provides a pocket tofacilitate the ready assembly and removal of the hinge pin, and whichalso cooperates with the door in such a manner that the enamel surfacewill not come into contact with the wall of the range during its openingmovement.

It further comprehends a novel concealed hinge mechanism for range doorswherein provision is made for the ready insertion of a wrench in orderto tighten the nuts which retain the hinge pins in assembled condition.

Other novel features of construction and advantage will hereinafter moreclearly appear in the detailed description and the appended claims.

For the purpose of illustrating the invention, I have shown in theaccompanying drawing a typical embodiment of it, which, in practice,will give satisfactory and reliable results. It is, however, to beunderstood that the various instrumentalities of which my inventionconsists can be variously arranged and organized and my invention is notlimited to the exact arrangement I and organization of theseinstrumentalities as herein set forth.

Figure 1 is a front elevation of a conventional range in conjunctionwith which concealed hinge mechanism embodying my invention is employed.

Figure 2 is a sectional view showing the door in its extreme openposition, vand showing in more detail the construction of the wall orframe of the range and the manner inwhich the door is hinged. 4

Figure 3 is a sectional plan View of a portion of the range, the sectionbeing taken in proximity to the hinge pin.

Similar numerals of reference indicate corresponding parts.

Referring to the dr'awing':-

1 designates'the right end wall orplate of a conventional range, and 2designates the front plate or wall which forms the door frame. The wall2 is provided with a rearwardly extending flange 3 to overhang theflanged end of the right end wall 1, and this front wall'2, at its frontportion, is deflected rearwardly as at 4, then laterally as at 5, thenoutwardly as at 6 to form avertically disposed recess '7. The front wallthen extends laterally as at 8 and has its free end por- 'tion deflectedinwardly as at 9 where, for example, an oven opening is formed, and thelaterally extending portion 8 is apertured at 10 for a purpose whichwill hereinafter clearly appear.

The front wall 2 is provided with a rearwardly extending flange 11. Theoven wall or plate 12 has a portion thereof outwardly deflected as at 13which overhangs the flange 11 and contributes to form a pocket 14 whichis open as at 15.

16 designates the door which is provided with a hinge support 17 whichis apertured as at 18 to receive the end of an L shaped hinge pin 19,which latter extends through an aperture 20 in the wall 6 and isprovided with a nut 21 in threaded engagement with the shank of thehinge pin and bearing against the rear face of the wall 6.

The door may be of any desired or conventional construction and may bemade up of one or more parts. As illustrated, it is provided with aninwardly extending flange 22 which, during the opening movement of thedoor 16, will contact with the hinge pin 19 and thus prevent theenameled outer face of the door contacting with the front wall which itwould do if it were not for this construction.

It will, of course, be understood that a hinge construction is providedin spaced relationship at the upper and lower portions of the door.

It will now be apparent with the door mounted on the hinge pins, theshank of the hinge pins can be inserted through the apertures 20 and thenut 21 can be tightened by the insertion of a socket wrench into thepocket 14 which is made large enough for this purpose.

In case the door is a fire door then the apertures 10 are provided, inorder to provide suflicient clearance for tightening the nut 21 by meansof an S wrench. These apertures 10 are preferably in the form of slots.

It will be apparent that in accordance with my present invention Iprovide a recessjnto which the rear end of the door extends and themounting for the hinge pins is such that the door, when closed, will besubstantially flush with the front Wall'or door frame of the range. Ialso provide a pocket opening into the oven so that the hinge pin can bequickly and readily secured in position and also an aperture in case thedoor is to be a fire door, in order that the nuts of the hinge pins canbe quickly and readily tightened.

My present invention provides a concealed hinge construction which willprovide more than a opening of the door and the door contributes withthe hinge pins to limit its opening movement so that the enameled faceof the door will not be injured by contact with the door frame or wallof the range. 7,

It will now be apparent that I havedevised a new and useful concealedhinge mechanism for range doors which embodies the features of advantageenumerated as desirable in the statement of the invention and the abovedescription, and while I have, in the present instance, shown anddescribed a preferred embodiment thereof which will give in practicesatisfactory and reliable results, it is to be understood that thisembodiment is susceptible of modification in various particulars withoutdeparting from the spirit or scope;of the invention or sacrificing anyof its advantages.

Having thus described my invention What I claim as new and desire tosecure by Letters Patent, is:

1. In a concealed hinge. mechanism for ranges, a front wall inwardlydeflected to form a recess at one side of a door opening, a door toclose said opening substantially flush, with said front wall, and spacedhinge pins "extending through a wall of said recess and concealed bysaid door, said hinge pins serving as stops to limit the extent ofopening movement of the door.

2. In a concealedhinge mechanism for ranges, a front wall having an ovenopening, and inwardly deflected at one side of said opening to form arecess, spaced hinge pins extending through awall of said recess, a doorto close said opening, mounted on said hinge pins and concealing saidhinge pins when closed, said door when closed being substantially flushwith said front wall, nuts in threaded engagement with the inner ends ofsaid hinge pins, and the wall of said oven in proximity to said nutsbeing inwardly deflected to provide clearance for the use of a wrench totighten said nuts. 7

3. In a concealed hinge mechanism for ranges, a wall having a dooropening, and a recess at one siderof said opening, hinge" pins extendingthrough said wall and into said recess, a door mounted on said hingepins and concealing them, and substantially flush with said wall whenclosed, and the opening closed by said door having one of its wallsprovided with pockets to provide access to secure them in position.

4. Ina concealed hinge mechanism for ranges, a wall having a dooropening and inwardly de fiected at one side of such opening to form arecess, and provided with slots at one side of said recess hinge pinsextending through said wall, a door mounted on said hinge pins, andsubstantially flush with said wall when closed, and nuts for said hingepins accessible for adjustment by insertion of a working tool throughsaid slots.

5. In a concealed hinged mechanism for ranges, a front wall deflectedrearwardly, laterally and outwardly to 'form a recess at one side of adoor opening, a door to close said opening and substantially flush withsaid front wall, 'and spaced hinged pins extending through a wall ofsaid recess and carrying said door, said pins being completely concealedby said door and limiting its opening movement.
